Dual Bootstrapped, 12 V MOSFET

Driver with Output Disable

ADP3120A

FEATURES

GENERAL DESCRIPTION

All-in-one synchronous buck driver

Bootstrapped high-side drive

One PWM signal generates both drives

Anticross conduction protection circuitry

The ADP3120A is a dual, high voltage MOSFET driver

optimized for driving two N-channel MOSFETs, the two switches

in a nonisolated synchronous buck power converter. Each

driver is capable of driving a 3000 pF load with a 45 ns propaga-

tion delay and a 25 ns transition time. One of the drivers can be

bootstrapped and is designed to handle the high voltage slew

rate associated with floating high-side gate drivers. The

ADP3120A includes overlapping drive protection to prevent

shoot-through current in the external MOSFETs.

for disabling the driver outputs

Meets CPU VR requirement when used with

Analog Devices Flex -Mode™¹controller

APPLICATIONS

Multiphase desktop CPU supplies

Single-supply synchronous buck converters

The

pin shuts off both the high-side and the low-side

MOSFETs to prevent rapid output capacitor discharge during

system shutdown.

The ADP3120A is specified over the commercial temperature

range of 0°C to 85°C and is available in 8-lead SOIC_N and

8-lead LFCSP_VD packages.

¹Flex-Mode is protected by U.S. Patent 6683441; other patents pending.
